DETAILED DESCRIPTION OF EMBODIMENTS Description of Embodiments of Present Disclosure

First, aspects of the present disclosure will be listed and described.

The wire harness of the present disclosure includes:

[1] a wire harness main body including an electric wire member and an outer cover member covering an outer circumference of the electric wire member; a first route-regulating member that is attached to an outer circumference of the outer cover member and regulates a route of the wire harness main body; and an attachment member that is attached to a portion of an outer circumference of the first route-regulating member in a lengthwise direction of the first route-regulating member, in which the first route-regulating member includes an insertion port that is open in a direction orthogonal to the lengthwise direction of the first route-regulating member and extends along the entire first route-regulating member in the lengthwise direction of the first route-regulating member, the attachment member includes a receiving portion covering a portion in a circumferential direction of the first route-regulating member, a lid covering the entire circumference of the first route-regulating member together with the receiving portion, first fixing portions that are respectively provided at two end portions of the receiving portion in a circumferential direction of the receiving portion, and second fixing portions that are respectively provided at two end portions of the lid in a circumferential direction of the lid, and fixing members that are each attached to the first fixing portion and the second fixing portion that overlap each other and each inhibit the first fixing portion and the second fixing portion from separating from each other, and the receiving portion and the lid hold the first route-regulating member.

According to this configuration, the first fixing portions are respectively provided at two end portions of the receiving portion in the circumferential direction, and the second fixing portions are respectively provided at two end portions of the lid in the circumferential direction. Also, each fixing member is attached to the first fixing portion and the second fixing portion that overlap each other, and the fixing member inhibits the first fixing portion and the second fixing portion from separating from each other. Doing so suppresses rattling between the receiving portion and the lid compared to a configuration in which the lid is integrated with the receiving portion via thin hinge portions and the lid is locked to the receiving portion through engagement using a claw portion in a closed state, for example. That is, in a configuration in which thin hinge portions and claw portions are provided, rattling between the receiving portion and the lid occurs at the hinge portions and the claw portions, but such rattling can be avoided. Therefore, the receiving portion and the lid can hold the first route-regulating member without rattling, and thus rattling between the first route-regulating member and the route-regulating member can be suppressed.

[2] It is preferable that the fixing member is attachable to the first fixing portion and the second fixing portion that overlap each other through sliding movement along a lengthwise direction of the attachment member, and is attached thereto.

According to this configuration, because the fixing member is attached through sliding movement along the lengthwise direction of the attachment member, it is possible to firmly inhibit the first fixing portion and the second fixing portion from separating from each other, for example. That is, in a configuration in which the fixing member is attached while the fixing member is bent from outside in the radial direction of the attachment member, for example, the fixing member is designed to be easily bent, and thus, the fixing member may be likely to come loose from the first fixing portion and the second fixing portion. However, this situation can be avoided.

[3] It is preferable that at least one of the first fixing portion and the second fixing portion has an engagement protrusion that engages with the fixing member in a direction in which the fixing member in an attached state is detached while allowing attachment of the fixing member, and that inhibits the fixing member from falling off.

According to this configuration, at least one of the first fixing portion and the second fixing portion has the engagement protrusion that engages with the fixing member in a direction in which the fixing member in an attached state is detached while allowing attachment of the fixing member, and that inhibits the fixing member from falling off. Therefore, it is possible to inhibit the fixing member from falling off.

[4] It is preferable that the engagement protrusion is provided on two sides of the fixing member in an attached state in the lengthwise direction of the attachment member.

According to this configuration, because the engagement protrusion is provided on two sides of the fixing member in an attached state in the lengthwise direction of the attachment member, the fixing member can be attached from either side in the lengthwise direction of the attachment member, for example.

[5] It is preferable that the fixing member is attachable to the first fixing portion and the second fixing portion that overlap each other from outside in a radial direction of the attachment member, and is attached thereto.

According to this configuration, because the fixing member is attached from outside in the radial direction of the attachment member, the fixing member can be easily attached, for example.

[6] It is preferable that the attachment member is a second route-regulating member that is attached to the outer circumference of the outer cover member and regulates the route of the wire harness main body, and the receiving portion is provided at an end portion in a lengthwise direction of the second route-regulating member and covers a circumferential portion of an end portion in the lengthwise direction of the first route-regulating member.

According to this configuration, because the receiving portion is provided at the end portion in the lengthwise direction of the second route-regulating member and covers the circumferential portion of the end portion in the lengthwise direction of the first route-regulating member, the first route-regulating member and the second route-regulating member are connected to each other in the lengthwise direction. Therefore, the route of the wire harness main body is regulated by the first route-regulating member and the second route-regulating member.

[7] It is preferable that the first route-regulating member regulates the route of a straight section, which is a section having a linear shape in the route of the wire harness main body, and the second route-regulating member regulates the route of a bent section, which is a section that is bent in the route of the wire harness main body.

According to this configuration, the route of the straight section is regulated by the first route-regulating member, and the route of the bent section is regulated by the second route-regulating member. As a result, the routes of the straight section and the bent section of the wire harness main body are continuously prevented from deviating from the desired routes.

DETAILS OF EMBODIMENTS OF THE PRESENT DISCLOSURE

Specific examples of the wire harness of the present disclosure will be described below with reference to the drawings. In each drawing, for convenience of description, portions of the configuration may be exaggerated or simplified. Also, the dimensional proportions of each portion may differ between drawings. In the present specification, “parallel” and “orthogonal” include not only the case of being strictly parallel and orthogonal, but also the case of being approximately parallel and orthogonal within a range in which the actions and effects of the present embodiment are exhibited. Note that the present disclosure is not limited to these examples, and is indicated by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

Overall Configuration of Wire Harness 10

A wire harness 10 shown in FIG. 1 is to be mounted in a vehicle V such as a hybrid vehicle or an electric vehicle, for example. The wire harness 10 electrically connects two or more on-board devices to each other. The on-board devices are electric devices mounted in the vehicle V. The wire harness 10 electrically connects, for example, an inverter M1 that is installed in a front portion of the vehicle V and a high-voltage battery M2 that is installed rearward of the inverter M1 in the vehicle V, to each other. The wire harness 10 has an elongated shape that extends in a front-rear direction of the vehicle V, for example. The wire harness 10 is routed in the vehicle V so that, for example, an intermediate portion in the lengthwise direction of the wire harness 10 passes outside the vehicle interior such as under the floor of the vehicle V.

The inverter M1 is, for example, connected to a motor (not shown) for driving wheels, which serves as a power source when the vehicle travels. The inverter M1 generates AC power from the DC power of the high-voltage battery M2, and supplies the AC power to the motor. The high-voltage battery M2 is, for example, a battery that is capable of supplying a voltage of several hundred volts.

The wire harness 10 includes a wire harness main body 11. The wire harness main body 11 includes an electric wire member 20 (electric wire) and a tubular outer cover member 30 (outer cover) that covers the outer circumference of the electric wire member 20. The wire harness 10 has connectors C1 and C2 that are respectively attached to two end portions of the electric wire member 20. One end portion in the lengthwise direction of the electric wire member 20 is connected to the inverter M1 via the connector C1, and the other end portion in the lengthwise direction of the electric wire member 20 is connected to the high-voltage battery M2 via the connector C2.

As shown in FIGS. 2 and 3 , the wire harness 10 includes a first route-regulating member 40 (first rout regulator) that is attached to the outer circumference of the outer cover member 30 and a second route-regulating member 60 (second route regulator) that is attached to the outer circumference of the outer cover member 30 and serves as an attachment member (attachment). The first route-regulating member 40 and the second route-regulating member 60 regulate the route along which the wire harness main body 11 is routed. Note that the first route-regulating member 40 and the second route-regulating member 60 are omitted from FIG. 1 .

Configuration of Electric Wire Member 20

As shown in FIGS. 4 and 6 , for example, the electric wire member 20 includes one or more electric wires 21 (e.g., two electric wires 21 in this embodiment) and a braided member 25 that collectively encloses the outer circumferences of the plurality of electric wires 21.

As shown in FIG. 6 , each electric wire 21 is a coated electric wire that includes a conductive core wire 22 and an insulating coating 23 that encloses the outer circumference of the core wire 22 and has insulating properties. Each electric wire 21 is, for example, a high-voltage electric wire that can support a high voltage and a large current. Each electric wire 21 may be, for example, a non-shielded electric wire that does not include an electromagnetic shield structure, or a shielded electric wire that includes an electromagnetic shield structure. Each electric wire 21 in the present embodiment is a non-shielded electric wire.

As the core wire 22, a stranded wire that is constituted by a plurality of metal strands twisted together, a single core wire that is constituted by a single conductor, or the like may be used, for example. As the single core wire, a columnar conductor that is constituted by one columnar metal rod with a solid internal structure, a tubular conductor with a hollow internal structure, or the like may be used, for example. As the core wire 22, a combination of a stranded wire, a columnar conductor, or a tubular conductor may be used. As the material of the core wire 22, a metal material such as a copper-based material or an aluminium-based material may be used, for example.

The insulating coating 23 covers, for example, all the way around the outer circumferential surface of the core wire 22. The insulating coating 23 is constituted by, for example, a resin material that has insulating properties.

The cross-sectional shape of each wire 21 taken along a plane that is orthogonal to the lengthwise direction of each wire 21, that is, the transverse cross-sectional shape of each wire 21, may be any shape. The transverse cross-sectional shape of each electric wire 21 may be, for example, a circular shape, a semi-circular shape, a polygonal shape, a square shape, a flat shape, or the like. The transverse cross-sectional shape of each electric wire 21 in the present embodiment is a circular shape.

The braided member 25 has, for example, an overall tubular shape that collectively encloses the outer circumferences of the plurality of electric wires 21. As the braided member 25, a braided wire in which a plurality of metal strands are braided or a braided wire in which metal strands and resin strands are braided in combination with each other may be used, for example. As the material of the metal strands, a metal material such as a copper-based material or an aluminium-based material may be used, for example. Although not shown in the drawings, the two end portions of the braided member 25 in the lengthwise direction are grounded at, for example, the connectors C1 and C2 (see FIG. 1 ).

Configuration of Outer Cover Member 30

As shown in FIG. 4 , the outer cover member 30 has a tubular shape that encloses all the way around the outer circumference of the electric wire member 20. The outer cover member 30 in the present embodiment is formed in a cylindrical shape. The outer cover member 30 is, for example, provided with a circumferential wall that is formed so as to be continuous all the way around the circumferential surface of the outer cover member 30. The outer cover member 30 seals, for example, the inside of the outer cover member 30 all the way around the circumferential surface of the outer cover member 30. The outer cover member 30 has, for example, a function of protecting the electric wire member 20 from flying objects and water droplets.

The outer cover member 30 is, for example, flexible and is easy to bend. Examples of the flexible outer cover member 30 include a resin corrugated tube and a rubber waterproof cover. The outer cover member 30 of this embodiment is a resin corrugated tube having an accordion shape whose diameter repeatedly increases and decreases in the lengthwise direction of the outer cover member 30. That is, the outer cover member 30 of this embodiment has an accordion structure in which large-diameter portions 31 and small-diameter portions 32 whose diameter is smaller than that of the large-diameter portions 31 are alternately and continuously provided along the lengthwise direction of the outer cover member 30. Each of the large-diameter portions 31 and the small-diameter portions 32 has, for example, a ring shape that encircles the outer cover member 30 once in the circumferential direction. As the material of the outer cover member 30, for example, a synthetic resin such as polyolefin, polyamide, polyester, or ABS resin can be used. Note that in FIGS. 1 to 3 , the outer cover member 30 is shown simplified for the sake of simplifying the drawings.

Configuration of First Route-Regulating Member 40 and Second Route-Regulating Member 60

As shown in FIGS. 2 and 3 , each of the first route-regulating member 40 and the second route-regulating member 60 holds the outer cover member 30. Each of the first route-regulating member 40 and the second route-regulating member 60 is harder than, for example, the outer cover member 30. Each of the first route-regulating member 40 and the second route-regulating member 60 has a hardness that makes it less likely to bend in a direction orthogonal to the lengthwise direction of the wire harness main body 11 compared to the outer cover member 30. As a result, the first route-regulating member 40 and the second route-regulating member 60 regulate the route of the wire harness main body 11. For example, the first route-regulating member 40 and the second route-regulating member 60 assist the outer cover member 30 so that the wire harness main body 11 does not deviate from the desired route as a result of bending under its own weight or the like.

As shown in FIG. 2 , the first route-regulating member 40 is provided along a portion in the lengthwise direction of the wire harness main body 11. For example, the first route-regulating member 40 is attached to the outer circumference of the outer cover member 30 along a straight section 11A, which is a straight section of the route of the wire harness main body 11. The first route-regulating member 40 regulates the route of the wire harness main body 11 in the straight section 11A. Here, the straight section 11A is a section in which the route of the wire harness main body 11 extends linearly in one direction. Note that one or more first route-regulating members 40 are provided depending on the route of the wire harness main body 11.

The second route-regulating member 60 is provided along a portion in the lengthwise direction of the wire harness main body 11. For example, the second route-regulating member 60 is attached to the outer circumference of the outer cover member 30 along a bent section 11B, which is a bent section of the route of the wire harness main body 11. The second route-regulating member 60 regulates the route of the wire harness main body 11 in the bent section 11B. Here, the bent section 11B is a section in which the route of the wire harness main body 11 is bent so as to deviate from a straight line. Note that one or more second route-regulating members 60 are provided depending on the route of the wire harness main body 11.

Configuration of First Route-Regulating Member 40

As shown in FIG. 6 , the first route-regulating member 40 covers a portion of the outer circumference of the outer cover member 30 in the circumferential direction of the outer cover member 30. The first route-regulating member 40 has a shape that covers a portion of the outer circumference of the outer cover member 30 in the circumferential direction of the outer cover member 30. The transverse cross-sectional shape of the first route-regulating member 40 is C-shaped overall. The first route-regulating member 40 covers, for example, an area greater than half of the outer circumference of the outer cover member 30. That is, the first route-regulating member 40 covers an area greater than half of the entire outer circumference of the outer cover member 30 in the circumferential direction of the outer cover member 30. As shown in FIG. 2 , the first route-regulating member 40 extends in the lengthwise direction of the outer cover member 30 in the straight section 11A. The first route-regulating member 40 is formed in a shape extending linearly in one direction, for example. The transverse cross-sectional shape of the first route-regulating member 40 is, for example, uniform over the entire length of the first route-regulating member 40 in the lengthwise direction of the first route-regulating member 40.

The first route-regulating member 40 is made of metal or resin, for example. The first route-regulating member 40 in the present embodiment is made of resin. As the material of the first route-regulating member 40, a synthetic resin such as polypropylene, polyamide, or polyacetal may be used, for example. The first route-regulating member 40 may be manufactured using a well-known manufacturing method such as extrusion molding or injection molding, for example. In this embodiment, the first route-regulating member 40 is an extruded product manufactured through extrusion molding. Therefore, the first route-regulating member 40 can be easily manufactured using an extrusion machine that extrudes a raw material of the first route-regulating member 40 in a lengthwise direction. Also, a plurality types of first route-regulating members 40 having different dimensions in the lengthwise direction can be manufactured using a single extrusion machine. A plurality types of first route-regulating members 40 having different dimensions in the lengthwise direction can be manufactured by cutting a base material of the first route-regulating member 40, which has been formed using a single extrusion machine, using a cutting device to a desired length, for example.

The first route-regulating member 40 has an insertion port 40X that is open in a direction orthogonal to the lengthwise direction of the first route-regulating member 40. The insertion port 40X extends along the entire first route-regulating member 40 in the lengthwise direction of the first route-regulating member 40. The first route-regulating member 40 has a first end portion 41 and a second end portion 42 that are two end portions in the circumferential direction of the first route-regulating member 40 and form the insertion port 40X. The first route-regulating portion 40 has a connection portion 43 that connects the first end portion 41 and the second end portion 42 to each other. In other words, the first route-regulating member 40 has the connection portion 43 formed so as to cover a portion of the outer cover member 30 in the circumferential direction thereof, the first end portion 41 and the second end portion 42 that are provided at two end portions of the connection portion 43, and the insertion port 40X formed by the first end portion 41 and the second end portion 42.

As shown in FIG. 6 , the connection portion 43 forms the main part of the first route-regulating member 40. The thickness in the radial direction of connection portion 43 is, for example, uniform in the circumferential direction of the first route-regulating member 40. The transverse cross-sectional shape of the connection portion 43 is formed, for example, in a shape that extends along the outer surface of the outer cover member 30. The transverse cross-sectional shapes of the first end portion 41, the second end portion 42, and the connection portion 43 are formed, for example, in an arc shape.

The first end portion 41 and the second end portion 42 are provided on mutually opposite sides in the circumferential direction of the first route-regulating member 40. The first end portion 41 and the second end portion 42 are provided spaced apart from each other with the insertion port 40X interposed therebetween in the circumferential direction of the first route-regulating member 40. In other words, the gap between the first end portion 41 and the second end portion 42 in the circumferential direction of the first route-regulating member 40 forms the insertion port 40X. As described above, the first route-regulating member 40 is formed in a C shape having the insertion port 40X in a portion in the circumferential direction of the first route-regulating member 40.

The transverse cross-sectional shapes of the leading ends of the first end portion 41 and the second end portion 42 are formed in curved shapes. The transverse cross-sectional shapes of the leading ends of the first end portion 41 and the second end portion 42 in this embodiment are formed in arc shapes.

The first route-regulating portion 40 has a protruding portion 45 that protrudes from the inner surface of the first end portion 41 and a protruding portion 46 that protrudes from the inner surface of the second end portion 42. The protruding portions 45 and 46 protrude toward the outer cover member 30 inserted into the first route-regulating member 40 and come into contact with the outer surface of the outer cover member 30. The protruding portions 45 and 46 are in contact with the outer surfaces of large-diameter portions 31 of the outer cover member 30. The protruding portion 45 protrudes from the inner surface of the leading end of the first end portion 41, for example. The protruding portion 46 protrudes from the inner surface of the leading end of the second end portion 42, for example. The transverse cross-sectional shapes of the protruding portions 45 and 46 are formed in curved shapes, for example. The transverse cross-sectional shapes of the protruding portions 45 and 46 in this embodiment are formed in arc shapes.

As shown in FIG. 3 , the protruding portions 45 and 46 extend in the lengthwise direction of the first route-regulating member 40. The protruding portions 45 and 46 extend along the entire length of the first route-regulating member 40 in the lengthwise direction of the first route-regulating member 40, for example.

The protruding portions 45 and 46 press the outer cover member 30 from the outer side of the outer cover member 30. The outer cover member 30 is elastically held by the protruding portions 45 and 46, and the connection portion 43. As a result, the connection between the first route-regulating member 40 and the outer cover member 30 is strengthened.

As shown in FIG. 6 , the opening width of the insertion port 40X, that is, the shortest distance between the first end portion 41 and the second end portion 42, is smaller than the outer diameter of the outer cover member 30.

When the first route-regulating member 40 is elastically deformed, the opening width of the insertion port 40X increases. When the outer cover member 30 is inserted into the insertion port 40X in a direction orthogonal to the lengthwise direction of the first route-regulating member 40, for example, the opening width of the insertion port 40X increases. Once the outer cover member 30 has been inserted into the first route-regulating member 40, the first route-regulating member 40 elastically returns to return to its original shape. As a result, the opening width of the insertion port 40X becomes smaller than the outer diameter of the outer cover member 30, and therefore the first route-regulating member 40 is attached to the outer circumference of the outer cover member 30.

Configuration of Second Route-Regulating Member 60

As shown in FIG. 2 , the second route-regulating member 60 is attached to a portion of the outer circumference of the first route-regulating member 40 in the lengthwise direction. The second route-regulating member 60 is attached to the outer circumference of an end portion in the lengthwise direction of the first route-regulating member 40. Also, the second route-regulating member 60 is attached to the outer circumference of the outer cover member 30 in the bent section 11B. The second route-regulating member 60 extends in the lengthwise direction of the outer cover member 30 in the bent section 11B. The second route-regulating member 60 is bent following the shape of the bent section 11B, for example.

The second route-regulating member 60 has a second route-regulating main body 61, a lid 62, and fixing members 63.

The second route-regulating main body 61, the lid 62, and the fixing members 63 that constitute the second route-regulating member 60 are made of metal or resin, for example. The second route-regulating main body 61, the lid 62, and the fixing members 63 in this embodiment are made of resin. As the materials of the second route-regulating main body 61, the lid 62, and the fixing members 63, for example, a synthetic resin such as polypropylene, polyamide, or polyacetal can be used. The second route-regulating main body 61, the lid 62, and the fixing members 63 may be manufactured using a well-known manufacturing method such as injection molding, for example.

The second route-regulating main body 61 includes a main body portion 64 and a receiving portion 65 (receiver).

The main body portion 64 covers a portion of the outer circumference of the outer cover member 30 in the circumferential direction of the outer cover member 30. The main body portion 64 has a shape that covers a portion of the outer circumference of the outer cover member 30 in the circumferential direction of the outer cover member 30. The transverse cross-sectional shape of the main body portion 64 is semi-cylindrical overall. The main body portion 64 covers half of the outer circumference of the outer cover member 30. As shown in FIG. 2 , the main body portion 64 extends in the lengthwise direction of the outer cover member 30 in the bent section 11B. The main body portion 64 is bent following the shape of the bent section 11B.

The receiving portion 65 is provided at an end portion in the lengthwise direction of the second route-regulating member 60, i.e., an end surface in the lengthwise direction of the main body portion 64. The receiving portion 65 covers a portion of the outer circumference of the first route-regulating member 40 in the circumferential direction of the first route-regulating member 40. The receiving portion 65 covers a circumferential portion of the end portion in the lengthwise direction of the first route-regulating member 40. The receiving portion 65 has a shape that covers a portion of the outer circumference of the first route-regulating member 40 in the circumferential direction of the first route-regulating member 40. The transverse cross-sectional shape of the receiving portion 65 is semi-cylindrical overall. The receiving portion 65 has a semi-cylindrical shape whose diameter is larger than that of the main body portion 64. The receiving portion 65 covers half of the outer circumference of the first route-regulating member 40.

The receiving portion 65 has first fixing portions 66. The first fixing portions 66 are respectively provided at two end portions of the receiving portion 65 in the circumferential direction thereof. The first fixing portions 66 protrude outward in a radial direction from the two end portions of the receiving portion 65 in the circumferential direction. As shown in FIG. 6 , the first fixing portions 66 each have a first mating surface 67 that is a flat surface, which is continuous with an end surface in the circumferential direction of the receiving portion 65, and extends in the radial direction of the second route-regulating member 60. Also, the first fixing portion 66 has a first inclined surface 68 that is on the side opposite to the first mating surface 67 and extends away from the first mating surface 67 outward in the radial direction of the second route-regulating member 60. The first inclined surface 68 has an engagement protrusion 69. As shown in FIG. 5 , two engagement protrusions 69 are provided in the lengthwise direction of the receiving portion 65. The engagement protrusions 69 are respectively provided near end portions of the receiving portion 65 in the lengthwise direction of the receiving portion 65. The engagement protrusions 69 are spherical. Specifically, the engagement protrusions 69 each have a shape obtained by cutting a portion of half or less of a sphere along one plane.

The lid 62 covers the entire circumference of the first route-regulating member 40 together with the receiving portion 65. Specifically, the lid 62 covers the entire outer circumference of the first route-regulating member 40 in the circumferential direction together with the receiving portion 65. The lid 62 of this embodiment covers a portion of the outer circumference of the first route-regulating member 40 and a site where the outer circumference of the outer cover member 30 is exposed from the insertion port 40X. The transverse cross-sectional shape of the lid 62 is semi-cylindrical overall. The lid 62 has a semi-cylindrical shape with the same diameter as the receiving portion 65. The lid 62 covers a portion of the outer circumference of the first route-regulating member 40 in the circumferential direction that is not covered by the receiving portion 65, i.e., half of the outer circumference of the first route-regulating member 40.

The lid 62 has second fixing portions 70. The second fixing portions 70 are respectively provided at two end portions of the lid 62 in the circumferential direction thereof. The second fixing portions 70 protrude outward in a radial direction from the two end portions of the lid 62 in the circumferential direction. As shown in FIG. 6 , the second fixing portions 70 each have a second mating surface 71 that is a flat surface, which is continuous with an end surface in the circumferential direction of the lid 62, and extends in the radial direction of the second route-regulating member 60. Also, the second fixing portion 70 has a second inclined surface 72 that is on the side opposite to the second mating surface 71 and extends away from the second mating surface 71 outward in the radial direction of the second route-regulating member 60. The second inclined surface 72 has an engagement protrusion 73. As shown in FIG. 5 , two engagement protrusions 73 are provided in the lengthwise direction of the lid 62. The engagement protrusions 73 are respectively provided near end portions of the lid 62 in the lengthwise direction of the lid 62. The engagement protrusions 73 are spherical. Specifically, the engagement protrusions 73 each have a shape obtained by cutting a portion of half or less of a sphere along one plane. That is, the second fixing portions 70 have the same shape as the first fixing portions 66.

The receiving portion 65 and the lid 62 are set so as to cover the entire circumference of the first route-regulating member 40 and hold the first route-regulating member 40 in a state in which the first fixing portions 66 and the second fixing portions 70 overlap each other and the first mating surfaces 67 and the second mating surfaces 71 overlap each other.

Each fixing member 63 is attached to the first fixing portion 66 and the second fixing portion 70 that overlap each other, and inhibits the first fixing portion 66 and the second fixing portion 70 from separating from each other. Specifically, each fixing member 63 includes a fixing connection portion 74, a first claw 75 that protrudes from one end of the fixing connection portion 74 and can come into contact with the first inclined surface 68, and a second claw 76 that protrudes from the other end of the fixing connection portion 74 and can come into contact with the second inclined surface 72. The first claw 75 and the second claw 76 are formed so as to protrude from two ends of the fixing connection portion 74 and approach each other toward the leading end side thereof. The fixing member 63 holds the first fixing portion 66 and the second fixing portion 70, which overlap each other, using the first claw 75 and the second claw 76 and thereby inhibits the first fixing portion 66 and the second fixing portion 70 from separating from each other.

The fixing member 63 is attachable to the first fixing portion 66 and the second fixing portion 70 that overlap each other through sliding movement along the lengthwise direction of the first route-regulating member 40, and is attached thereto. As shown in FIG. 5 , the fixing member 63 is attached between the engagement protrusions 69 and 73 in the lengthwise direction of the second route-regulating member 60. In other words, the engagement protrusions 69 and 73 are provided on two sides of the fixing member 63 in an attached state in the lengthwise direction of the second route-regulating member 60. Here, the engagement protrusions 69 and 73 allows attachment of the fixing member 63 through sliding movement along the lengthwise direction of the second route-regulating member 60. That is, the engagement protrusions 69 and 73 protrude to an extent that, when attaching the fixing member 63, the first claw 75 and the second claw 76 of the fixing member 63 can move over the engagement protrusions 69 and 73 as a result of the fixing member 63 slightly bending, for example. Also, the engagement protrusions 69 and 73 engage with the fixing member 63 in a direction in which the attached fixing member 63 is detached and inhibit the fixing member 63 from falling off. That is, the engagement protrusions 69 and 73 engage with the fixing member 63 to an extent that the attached fixing member 63 does not undergo sliding movement along the lengthwise direction of the second route-regulating member 60 even when a small force such as vibration is applied to the second route-regulating member 60.

Also, as shown in FIG. 2 , the wire harness 10 includes a slide regulating member 77 that regulates sliding movement of the first route-regulating member 40 in the lengthwise direction of the outer cover member 30, for example. The wire harness 10 includes a slide regulating member 78 that regulates sliding movement of the second route-regulating member 60 in the lengthwise direction of the outer cover member 30, for example. Cable ties made of resin or metal, crimp rings, adhesive tape, or the like can be used as the slide regulating members 77 and 78, for example. The slide regulating members 77 and 78 of this embodiment are pieces of adhesive tape. The slide regulating member 77 is wound around the end portion of the first route-regulating member 40 that is not connected to the second route-regulating member 60, and the outer cover member 30. The slide regulating member 78 is wound around the end portion of the second route-regulating member 60 that is not connected to the first route-regulating member 40, and the outer cover member 30.

Next, operation of this embodiment will be described.

The state in which the receiving portion 65 and the lid 62 hold the first route-regulating member 40 is maintained by the fixing members 63. Therefore, the state in which the first route-regulating member 40 and the second route-regulating member 60 are connected to each other is maintained. Thus, the route of the wire harness main body 11 is continuously regulated.

Next, effects of the above-described embodiment will be described below.

(1) The first fixing portions 66 are respectively provided at two end portions of the receiving portion 65 in the circumferential direction thereof, and the second fixing portions 70 are respectively provided at two end portions of the lid 62 in the circumferential direction thereof. Also, each fixing member 63 is attached to the first fixing portion 66 and the second fixing portion 70 that overlap each other, and the fixing member 63 inhibits the first fixing portion 66 and the second fixing portion 70 from separating from each other. Doing so suppresses rattling between the receiving portion 65 and the lid 62 compared to a configuration in which the lid 62 is integrated with the receiving portion 65 via thin hinge portions and the lid 62 is locked to the receiving portion 65 through engagement using a claw portion in a closed state, for example. That is, in a configuration in which thin hinge portions and claw portions are provided, rattling between the receiving portion 65 and the lid 62 is likely to occur at the hinge portions and the claw portions, but such rattling can be avoided. Therefore, in this embodiment, the receiving portion 65 and the lid 62 can hold the first route-regulating member 40 without rattling, and it is possible to suppress rattling of the first route-regulating member 40 and the second route-regulating member 60. As a result, it is possible to suppress damage at the attachment site where the first route-regulating member 40 and the second route-regulating member 60 are attached to each other, and thus to stably regulate the route of the wire harness main body 11.

(2) Because each fixing member 63 is attached through sliding movement along the lengthwise direction of the second route-regulating member 60, it is possible to firmly inhibit the first fixing portion 66 and the second fixing portion 70 from separating from each other, for example. That is, in a configuration in which the fixing member is attached while the fixing member is bent from outside in the radial direction of the second route-regulating member 60, for example, a fixing member is designed to be easily bent, and thus, the fixing member may be more likely to come loose from the first fixing portion 66 and the second fixing portion 70. However, this situation can be avoided.

(3) Because the first fixing portion 66 and the second fixing portion 70 respectively have the engagement protrusion 69 and the engagement protrusion 73 that engage with the fixing member 63 in a direction in which the fixing member 63 in an attached state is detached while allowing attachment of the fixing member 63, and that inhibit the fixing member 63 from falling off, it is possible to inhibit the fixing member 63 from falling off.

(4) Because the engagement protrusions 69 and 73 are provided on two sides of the fixing member 63 in an attached state in the lengthwise direction of the second route-regulating member 60, the fixing member 63 can be attached from either side in the lengthwise direction of the second route-regulating member 60, for example.

(5) The attachment member to be attached to the first route-regulating member 40 is the second route-regulating member 60 that is attached to the outer circumference of the outer cover member 30 and regulates the route of the wire harness main body 11. Also, because the receiving portion 65 is provided at the end portion in the lengthwise direction of the second route-regulating member 60 and covers the circumferential portion of the end portion in the lengthwise direction of the first route-regulating member 40, the first route-regulating member 40 and the second route-regulating member 60 are connected to each other in the lengthwise direction. Therefore, the route of the wire harness main body 11 is continuously regulated by the first route-regulating member 40 and the second route-regulating member 60.

(6) The route of the straight section 11A of the wire harness main body 11 is regulated by the first route-regulating member 40, and the route of the bent section 11B of the wire harness main body 11 is regulated by the second route-regulating member 60. As a result, the routes of the straight section 11A and the bent section 11B of the wire harness main body 11 are continuously prevented from deviating from the desired routes.

Other Embodiments

The above embodiment can be modified and implemented as follows. The above embodiment and the following modifications can be implemented in combination with each other as long as no contradiction arises.

-   -   Although the first fixing portion 66 and the second fixing         portion 70 respectively have the engagement protrusions 69 and         73 in the above-described embodiment, the present disclosure is         not limited to this. A configuration may be adopted in which         either the first fixing portion 66 or the second fixing portion         70 has an engagement protrusion, or a configuration may be         adopted in which the first fixing portion 66 and the second         fixing portion 70 do not have an engagement protrusion.     -   Although the engagement protrusions 69 and 73 are provided on         two sides of the fixing member 63 in an attached state in the         lengthwise direction of the second route-regulating member 60 in         the above-described embodiment, the present disclosure is not         limited to this, and the engagement protrusions 69 and 73 may be         modified to have other configurations.

As shown in FIG. 7 , for example, a configuration may be adopted in which the engagement protrusions 69 and 73 are provided on one side of the fixing member 63 in the lengthwise direction of the second route-regulating member 60 in the attached state, and regulating portions 80 that do not allow attachment of the fixing member 63 are provided on the other side of the fixing member 63. The regulating portions 80 extend from end portions of the first fixing portion 66 and the second fixing portion 70 in the circumferential direction of the second route-regulating member 60. This allows attachment of the fixing member 63 to the first fixing portion 66 and the second fixing portion 70 that overlap each other from one side in the lengthwise direction of the second route-regulating member 60, and the regulating portions 80 regulate the fixing member 63 such that the fixing member 63 does not move to the other side in the lengthwise direction of the second route-regulating member 60.

-   -   Although the fixing member 63 is attachable to the first fixing         portion 66 and the second fixing portion 70 that overlap each         other through sliding movement along the lengthwise direction of         the second route-regulating member 60 in the above-described         embodiment, the present disclosure is not limited to this, and a         configuration may be adopted in which the fixing member 63 is         attachable from another direction.

Modifications can be made as shown in FIGS. 8 and 9 , for example. A fixing member 90 in this example is attachable to the first fixing portion 66 and the second fixing portion 70 that overlap each other from outside in the radial direction of the second route-regulating member 60, and is attached from outside in the radial direction of the second route-regulating member 60. Note that the angle of the first inclined surface 68 of the first fixing portion 66, the angle of the second inclined surface 72 of the second fixing portion 70, and the shape and the materials of the fixing member 90 in this example are modified such that the fixing member 90 can be attached while the fixing member 90 is being bent from outside in the radial direction of the second route-regulating member 60. Also, in this example, the engagement protrusions 69 and 73 of the above-described embodiment are removed, and regulating portions 91 are provided. The regulating portions 91 extend in the circumferential direction of the second route-regulating member 60 from end portions of the first fixing portion 66 and the second fixing portion 70 in the lengthwise direction of the second route-regulating member 60. Also, the regulating portions 91 of this example are provided over the entire circumference of the second route-regulating member 60.

As a result, the fixing member 90 is attached from outside in the radial direction of the second route-regulating member 60, and thus the fixing member 90 can be easily attached, for example. Further, accordingly, sliding movement of the receiving portion 65, the lid 62, and the fixing members 90 in the lengthwise direction of the second route-regulating member 60 is firmly suppressed by the regulating portions 91.

-   -   The second route-regulating member 60 of the above-described         embodiment is formed so as to regulate the route of the bent         section 11B of the wire harness main body 11, but there is no         limitation to this. For example, the second route-regulating         member 60 may be changed to a shape that regulates the route of         the straight section 11A of the wire harness main body 11. The         second route-regulating member 60 in this case is changed to,         for example, a shape in which the bent shape of the main body         portion 64 extends linearly.     -   Although the second route-regulating member 60 is embodied as an         attachment member attached to the first route-regulating member         40 in the above-described embodiment, the present disclosure is         no limited to this. The attachment member may be embodied as a         vehicle attachment member for attaching the first         route-regulating member 40 to the vehicle V, for example.     -   The structure of the first route-regulating member 40 of the         above-described embodiment can be changed as appropriate. For         example, as long as the first route-regulating member 40 has the         insertion port 40X and has a structure with which the first         route-regulating member 40 can be attached to the outer         circumference of the outer cover member 30, there is no         particular limitation to the other structures.     -   The protruding portion 45 of the above-described embodiment may         be provided at a position farther from the insertion port 40X         than the leading end of the first end portion 41 in the         circumferential direction of the first route-regulating member         40.     -   The protruding portion 46 of the above-described embodiment may         be provided at a position farther from the insertion port 40X         than the leading end of the second end portion 42 in the         circumferential direction of the first route-regulating member         40.     -   The protruding portions 45 and 46 of the above-described         embodiment may also be partially provided in the lengthwise         direction of the first route-regulating member 40.     -   At least one of the protruding portions 45 and 46 of the         above-described embodiment may be omitted.     -   In the first route-regulating member 40 of the above-described         embodiment, the thickness in the radial direction of the         connection portion 43 may be changed in the circumferential         direction.     -   The shape of the connection portion 43 in the first         route-regulating member 40 of the above-described embodiment is         not limited to an arc shape, and can be changed to, for example,         an elliptical arc shape, a U shape, or the like.     -   In the above-described embodiment, the first route-regulating         member 40 and the second route-regulating member 60 are more         rigid than the outer cover member 30, but there is no limitation         to this, and the hardness may be less than or equal to that of         the outer cover member 30. That is, the first route-regulating         member 40 and the second route-regulating member 60 need only         act so that the wire harness main body 11 is less likely to bend         than the wire harness main body 11 in the state where the first         route-regulating member 40 and the second route-regulating         member 60 are not attached.     -   For example, the outer cover member 30 in the above-described         embodiment may be a resin corrugated tube with a metal layer         that contains a metal material, formed on the outer surface         thereof.     -   The outer cover member 30 in the above-described embodiment is         not limited to being a corrugated tube, and may be an outer         cover member that is not provided with a large-diameter portion         31 or a small-diameter portion 32, for example.     -   The outer cover member 30 in the above-described embodiment may         have a slit that extends in the lengthwise direction of the         outer cover member 30.     -   Although the electric wires 21 in the above-described embodiment         are high-voltage electric wires, the present disclosure is not         limited to such a configuration. For example, the electric wires         21 may be low-voltage electric wires.     -   In the electric wire member 20 in the above-described         embodiment, an electromagnetic shield member is embodied as the         braided member 25. However, the present disclosure is not         limited to such a configuration. For example, the         electromagnetic shield member in the electric wire member 20 may         be embodied as a metal foil.     -   The braided member 25 of the electric wire member 20 in the         above-described embodiment may be omitted.     -   In the above-described embodiment, the number of electric wires         21 included in the electric wire member 20 is two. However, the         present disclosure is not limited to such a configuration. The         number of electric wires 21 may be one or three or more.     -   The positional relationship between the inverter M1 and the         high-voltage battery M2 in the vehicle V is not limited to that         in the above-described embodiment, and may be changed as         appropriate depending on the vehicle configuration.     -   In the above-described embodiment, a plurality of on-board         devices to which the wire harness 10 is to be electrically         connected are embodied as the inverter M1 and the high-voltage         battery M2. However, the present disclosure is not limited to         such a configuration. The plurality of on-board devices to which         the wire harness 10 is to be electrically connected are not         particularly limited as long as they are electric devices to be         mounted in the vehicle V.     -   The embodiments disclosed herein are illustrative in all aspects         and should not be considered restrictive. The scope of the         present disclosure is indicated by the scope of claims, not the         above-mentioned meaning, and is intended to include all         modifications within the meaning and scope equivalent to the         scope of claims.
